doubling the solution list.
* ComputeSolutions() will now check if solving the Sudoku is affordable for
this algorithm (at least 1/6th of the fields must be known). This fixes
one part of bug #1435.
* SudokuView now checks if the Sudoku is already solved before trying to
fill in a value from the solution (and then it did not find a free spot,
surprisingly). This fixes the other part of bug #1435.
* SudokuView now beeps if there was no solution.

* FindPanel::SetUpAddRemoveButtons() called Window()->FindView() but did not
check if Window() was NULL.
* BWindow now always checks the result of a BAutolock - this is why Tracker
got away with this bug on BeOS; NULL windows cannot be locked...

its shells has been terminated. Usually the thread reading from the tty
master would notice when all slaves have been closed, but they won't be
closed when the shell started a background job that's still living.
Unfortunately there are race conditions in the terminal that can lead to
deadlock when a session is closed. The service threads usually happily
lock the window, while the (locked) window would wait for the service
threads to quit.

the host platform's <signal.h> to build the signal name array from. We
use a hand-edited signames.h when cross-compiling for Haiku, now.
The shell does now show the correct signal names when having been
compiled under Linux. Moreover we avoid bug #1428 (mksignames being
broken under FreeBSD).

cicrumstances.

is used instead of death_entry for team::dead_children.
* Added team::{stopped,continued}_children, which, analoguously to
dead_children, are used to track the state of stopped/continued
children.
* A team does have a job_control_entry, which is allocated at team
creation time. It will be inserted into the parent's
{stopped,continued}_children lists as the team's main thread is
stopped/continued and removed when waitpid() retrieves the child
state. When the team dies the entry is detached from the team and goes
into the parent's dead_children list.
* Removed the wait_for_any field from team_dead_children. It was solely
used to avoid deletion of the contained entries in certain situations.
wait_for_child() (the waitpid() backend) always deletes an entry now,
regardless of whether other threads are waiting; that's in
accordance with the waidpid() specification. wait_for_thread() removes
the entry only, if the caller is the parent of the respective team.
* Introduced team_set_job_control_state() which performes the job
control entry transitions between the respective lists and wakes up
threads waiting in wait_for_child(). It is invoked on team death and
when the team's main thread receives job control signals.
* Reorganized wait_for_child(). It handles WCONTINUED and WUNTRACED now,
too. Removed a block that interpreted the supplied ID as thread ID.
* Added missing parts in waitpid().
Job control starts to work, though it seems to have some glitches.

* Added class InterruptsSpinLocker, which disables interrupts and
acquires a spinlock all in one.

variable. Due to C code including the header I had to turn it from and
aggregated member to a pointer. I'm very close to starting to convert
all remaining .c to .cpp files. :-/
* Got rid of the "waiters" field. It was only written, never read.

access the pci_device object.

* Removed left-over commented C implementation.
* It is now possible for a thread to wait for more than one condition
variable at a time.
* Made waiting for condition variables optionally interruptable.
* Renamed Notify() method to NotifyAll() and added a NotifyOne(), so
that it is now possible to wake up only one of the waiting threads.
Pretty much untested at the moment.

in the ticket comments, and move the rounding of drawing command coordinates
into ViewLayer::ConvertToTopForDrawing() instead of handling it in
